Review: BMW 3 Series (2019)

More spacious than before. Upgraded engines. Very refined.

Saloons not as practical as SUVs in many people's eyes.

BMW 3 Series (2019): At A Glance

The BMW 3 Series is wider, longer and lighter than its predecessor - with BMW insisting that it will remain at the top of its class in terms of handling. Still clearly a 3 Series, the latest model features a larger kidney grille and headlights similar to the bigger 5 Series. 

A longer wheelbase translates to a roomier cabin. BMW is promising an extra 11mm of rear legroom and more headroom for those in the front and back. Larger doors should make getting in and out of the new 3 Series easier, while the rear seats can accommodate three child seats. With the rear seats left up, boot space is 480 litres, while the rear seats can be dropped 40:20:40 to increase luggage capacity.

There's more kit as standard, with the entry-level model featuring an 8.8-inch central touchscreen infotainment system, increasing to a 10.3-inch system on the M Sport model. Apple CarPlay is standard across the range, although drivers will have to pay for a subscription service after the first year.

Like the Mercedes-Benz 'Hey Mercedes' personal assistant that made its passenger car debut in the A-Class, drivers and passengers in the new 3 Series will be able to access functions and retrieve information by saying 'Hey BMW'.

Described as 'the ideal co-driver', the personal assistant will learn your routines and habits allowing it to answer questions and even provide casual conversation ('Hey BMW, what is the meaning of life?' is an example provided by BMW).

The 3 Series comes with a digital key as per bigger models in the range, allowing it to be locked and unlocked from a smartphone.

From launch, buyers can choose from a range of four-cylinder engines in the 320d diesel and 330i petrol. The diesel produces 190PS with peak torque of 400Nm, taking it to 62mph in 7.1 seconds (automatic: 6.8 seconds), while the four-wheel-drive xDrive version takes 6.9 seconds.

I can't drive my car with the warning light on but the dealer won't look at it. What do I do?

Six weeks ago, my six-month-old BMW G20 3 Series had an engine management light come on. I called my dealer and booked it in (10 days was first appointment). I asked if it was okay to run with this light on for 10 days and they asked me to call BMW emergency services to get a technician to look at it. The technician told me I couldn't run it and he would arrange for my car to be looked at immediately. It was to be taken to the dealer and a hire car would be provided and I should be at the dealer at 4pm that day. Another agent then called me to confirm and arrange the Hire Car. Got to the dealer and of course they knew nothing about it, no hire car and a 70 miles round trip wasted. I called BMW Emergency and there reply was " there's nothing in the notes so nothing I can do". I raised a complaint with BMW and got a letter 2 days later saying they were looking into it. Its now 6 weeks and I've heard nothing, I escalated to BMW and their stance is that its not their problem as BMW Emergency service is with Allianz not them. My stance is that my warranty (of which BMW emergency service is part) is with BMW and if they choose to subcontract it, that's their issue not mine. What's your advice on this one?
The line of responsibility here stops with the dealer that sold you the car. Tell them in writing that you want the car fixed or replaced. If they are unable to do either of these things. you will need to seek legal advice to reject the car and get a refund (minus a fair deduction for the usage you have already had fro the vehicle) . For legal help, start with Citizens Advice (it's free). For your consumer rights, see:
